ABSTRACT:
A blood aspiration assembly and method has proximal, intermediate and distal tubing, an adjustable volume reservoir and an aspirator receiver. The receiver has a housing with a rigid casing and a resilient plug, and a liquid flow chamber. The resilient plug has a slit or perforation to allow passage of a blunt needle therethrough. The plug can have two parts of different compliance, which aligned slits or perforations. The blunt needle tip can be rounded or flat, with a side opening for the needle bore. The contour of the needle tip and the design of the plug are correlated such that the working force required to penetrate the needle tip into the plug perforation is considerably less than the force required for said needle tip to penetrate normal intact human skin of the hands or arms.
